Hahah. I can solve that in a later patch :)

It is perfectly valid to have multiple CC Picture User Data
for the same frame. Instead of using the first side_data
potentially present with the A53_CC type, iterate over all
side_data.

What is the current behaviour?
Shouldn't the decoder output all pages as for a video file?

Okay I found "fmemopen()". I'll see if I can use it with
unzOpenCurrentFilePassword(). Please do tell if there
is a better solution though.

I have the meta chunk loaded into a buffer.
I searched a lot but I couldn't find a way to decompress
a password protected zip buffer.
I saw zlib is used in the code base, so went through it.
Found a function "decompress()" but it didn't take a
password as argument. I found another function

Option "-page N" (page index N starts from 1) can now be used to specify which
TIFF page/subfile to decode.

Hi Tomas
Sony defined many kinds of meta data.
e.g. SMPTE RDD 18:2012
Acquisition Metadata Sets for
Video Camera Parameters
I think the file created by -vcodec copy is a general op1a mxf file.
It can not pass Sony's mxf file verifier, which means their camera can
not play those files.
Yufei.
Yup, will do.
I made it before I realized there were size limits. Pushed a patch just in case.

Hi Tomas
From my tests, I find FFmpeg can demux XAVC mxf files from Sony and
find the video stream is actually h.264 data. This is very good to us.
Actually Sony XAVC mxf has a lot of restrictions on mxf file wrapper and
h.264 data.
But I don't know how to specify the it or it's not supported

By reading some more RFCs it is possible to find examples where some integers
parameters are greater than 32 (see RFC-6416, 7.4)
Instead I propose to check just check the eventual integer overflow.
